SURE-FLEX" SPACER COUPLINGS, continued
5. Check parallel alignment by placing a straightedge across the two coupling flanges and. measuring the maximum offset at various points around the periphery
of the coupling. 00 NOT rotate the coupling. If the maximum offset exceeds the figure shown under "Parallel" in Table 3, realign the coupling.
6. Check angular alignment with a micrometer or caliper. Measure from the outside of one flange to the outside of the other at intervals around the periphery of the
coupling. Determine the maximum and minimum dimensions.
DO NOT rotate the coupling. The difference between the maximum and minimum must not exceed
the figure given under "Angular" in Table 3.
If
a correction is necessary, be sure to recheck the parallel alignment. (Note:
For maximum life, keep misalignment values as near to zero as possible.)
NOTE: Periodically check elastomeric coupling sleeves for any visible evidence of deterioration. If deterioration is apparent, the coupling sleeve must be
replaced.
NOTE: Values shown above apply If the actual torque transmitted is more than 1/4 the coupling rating. For lesser torque. reduce
the above values by
112.
"Type
H sleeves (orange) should not be used as direct replacements for EPDM or Neoprene sleeves
(black) or with J or B flanges.
7. If the coupling employs the two-piece sleeve with the wire ring. force the ring into its groove in the center of the sleeve. It may
be necessary to pry the ring into position with a blunt screwdriver.
8. Check safety codes and install protective guards or shields as required.
